Under Armour Fly By Racerback Women's Running Tank Top Built for a fitted, next-to-skin fit without the squeeze. This Tank Top provides technologies that help you advance your game and offers extreme amounts of comfort. The soft, ultra-lightweight fabric that this tank top has to offer delivers superior breathability and incredible comfort. A large, open-hole performance mesh back and side panels offer unrivalled breathability allowing air to permeate the entire top keeping you cool. Under Armour have added their signature moisture transport system that wicks sweat as it's produced, then transfers it to the outer layers of the fabric where it can then be evaporated easily ensuring you stay cool dry and comfortable. Flatlock seams create a slim, chafe-free silhouette, whilst a feminine scoop neck and slight drop-tail offers just the right amount of coverage. A skinny racerback with keyhole detail unlocks serious range of motion, whilst 360 Degrees reflectivity offers extra safety during low-light runs.
